Then the staff pushes the second clamping plate 5, and the second lifting rod 86 slidably connected inside the second clamping plate 5 drives the upper lower pressure frame 6 and the lower pressure plate 7 to move synchronously. When it moves to a certain distance, the second clamping plate 5 contacts the arc surface of the oil cylinder bottom earring, and then the second motor 817 is started to drive The transmission shaft 814 rotates forward and reverse, and the transmission shaft 814 drives the second bevel gear 816 to rotate through the two first bevel gears 815 thereon, so that the two second screw rods 89 rotate forward and reverse, thereby causing the lifting plate 84 to reciprocate up and down, and the lifting plate 84 drives the first lifting rod 85 and the second lifting rod 86 to move up and down through the slider 812, so that the three lower pressure frames 6 and the lower pressure plate 7 inside the lower pressure frame 6 move up and down synchronously with the first lifting rod 85 and the second lifting rod 86, thereby realizing the downward pressure and fixation of the lower pressure plate 7 on the top surface of the cylinder bottom earring of the oil cylinder, and the wall thickness reserved for the cylinder bottom earrings of different sizes is different. By rotating the bolt 9, the restriction on the lower pressure plate 7 is released, and the staff moves the position of the lower pressure plate 7 in the lower pressure frame 6. The moving distance is determined according to the thick wall reserved for the cylinder bottom earring.
